JOHN ISAAC ALLMAN, OF MORGANTOWN, WEST VIRGINIA.

CHERRY-STONER.

Specification of Letters Patent;

Patented Sept. 5, 1916.

Application filed January 7, 1916. Serial No. 70,818.

To all whomz't may concern:

Be it known that I, JOHN ISAAC ALL- MAN, a citizen of the United States, residing at Morgantown, in the county of Monongalia and State of est Virginia, have invented new and useful Improvements in Cherry-Stoners, of which the following is a specification.

This invention relates to improvements in machines for extracting the stones from cherries.

In carrying out the present invention, it

is my purpose to provide a cherry stoner' wherein the lower end of the hopper will be connected with a throat formed of two longitudinal sections having the confronting ends thereof spaced apart and the spaces alining respectively with slots formed in the lower portion of the hopper at diametrically 0p posite points to receive the stone extracting disk, the sections of the throat being capable of movement toward and away from the respective sides of the disk automatically to permit stones of various sizes to pass through the throat.

It. is also my purpose to improve and simplify the general construction of cherry stoners and to provide a stone extracting device wherein the throat sections will be guided in their movements and wherein the component parts will be so arranged and correlated as to reduce the possibility of derangement to a minimum.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the claims.

In the accompanying drawings; Figure 1 is a View in side elevation of a cherry stoning device constructed in accordance with the present invention. Fig. 2 is a view in end elevation of the same. Fig. 3 is a vertical longitudinal sectional view through the stoner. Fig. 4 is a horizontal longitudinal sectional View therethrough. Fig. 5 is a transverse sectional View through the same. Fig. 6 is a similar view taken on a plane parallel with Fig. 5.

Referring now to the drawings in detail, 1 desi nates a baseboard having one end thereof bifurcated to form parallel supporting legs 2, 2. Mounted upon the upper surfaces of the respective supporting legs 2, 2 are blocks 3, 3 havin the confronting surfaces thereof respective y formed to provide alining bearings 4, alining guideways 5 substantially rectangular in cross section, and coaxial bores 6. In the present instance, the guidemiys 5 are arranged in advance of the bearings 4:, while the bores 6 are arranged forwardly of the guideways 5 and disposed adjacent to the outer ends of the blocks 3. Fastened to the upper surface of the base 1 behind the bifurcated end thereof and upstanding therefrom is a supporting bracket 7 and secured to the upper end of the supporting bracket 7 is a feed hopper 8 adapted to receive the cherries to be stoned and preferably formed of two sections 9, 9 secured to each other in some suitable manner. The lower or discharge end of the hopper 8 terminates in the bifurcated portion of the base 1 and is disposed between the bearings 4 and the guideways 5 and formed in the discharge end portion of the hopper 8 at diametrically opposite points are slots 10, while formed integral with the lower ends of the sections constituting the hopper and projecting forwardly from such ends are throat forming sections 11, 11 respectively having the confronting ends thereof spaced apart and the spaces 12 between such ends alining respectively, with the slots 10 in the lower end portion of the hopper. Journaled in the alining bearings 4: is a shaft 13 and one end of the shaft projects beyond the adjacent bearing and is equipped with an operating handle 14.

Disposed concentrically of the shaft 13 between the bearings 4 and fixed to such shaft is a stone extracting disk 15 having each face thereof formed with radially extending curved ribs 16. This disk 15 works in the spaces 12 and the slots 10 and in the rotation thereof moves across the lower end portion of the hopper and the ribs 16 remove the meat from the cherries and force the stones slowly and gradually through the lower end of the hopper and the throat formed of the sections 11 and discharge such stones or seeds from the outer end of the throat. In the presence instance, a substantially V-shaped metal chute 17 has the upper extremities of the limbs thereof fastened to the under surfaces of the respective legs 2 and this chute surrounds the discharge end of the throat formed of the sections 11 to receive the seedsfrom such throat. The sections of the throat are equipped with laterally projecting guides 18 respectively and these guides Work in the guideways 5, while disposed within the bores 6 are coiled expansion springs 19 respectively having the inner ends bearing against the respective sections 11 and act to hold the sections normally against the respective sides of the stone extracting disk.

In the use of the device the base is placed upon a suitable receptacle and the meat taken from the stones by the ribs 16 is delivered to such receptacle. As the stones pass through the throat the sections 11 move outwardly, when relatively large stones are discharged from the chute, against the action of the springs 19 and as soon as the large stones have been discharged the springs react to restore the sections to normal position.

lVhile I have herein shown and described one preferred form of my invention by way of illustration, I wish it to be understood that I do not limit or confine myself to the precise details of construction herein described and delineated, as modification and variation may be made within the scope of the claims without departing from the spirit of the invention.

I claim:

1. A cherry stoner comprising a hopper having the outlet end portion formed at diametrically opposite points with slots, a discharge throat connected with the outlet end of said hopper and formed of two longitudinal sections having the confronting edges spaced apart and the spaces between such edges alining with said slots respectively, a stone extracting disk rotatable through said Copies of this patent may be obtained for five cents each, by addressing the charge throat connected with the outlet end of said hopper and formed of two longitudinal sections having the confronting edges spaced apart and the spaces between such edges alining with said slots respectively, a

stone extracting disk rotatable through said slots and spaces, blocks disposed at the opposite sides of said throat and formed with alining guideways, guides on said throat sections respectively working within said guideways, and means carried by said blocks respectively and bearing against the sections of said throat and acting to hold the said sections normally against the disk and permit outward movement of the sections to accommodate stones of various sizes.

In testimony whereof I aflix my signature in presence of two witnesses.

JOHN ISAAC ALLMAN.
